Notes. Columns are from left to right as follows: (1) object names; (2) extinction values in the BLR are taken from Schnorr-Müller et al. (2016), and ( • )extinction values in the BLR are estimated in this study using the same method provided by Schnorr-Müller et al. (2016); (3) FWHMs of Hα emission line; (4) FWHMs of Hβ (or Paβ) emission line; (5) black hole masses estimated from the following methods (for the different sections of the table) from top to bottom: (5A) Hα – FWHM (extinction-corrected), and (5B) megamaser disk, (5C) LLAMA MBH–σ⋆; (6) extinction-corrected black hole masses estimated from the Hβ–σLine (or Paβ – FWHM); (7) accretion rates; (8) Eddington ratios; and (9) offset from the MBH–σ⋆ relation of KH13 for given σ⋆. The first section of the table lists LLAMA Seyfert (Sy) 1−1.5 AGNs, the second section lists the three LLAMA Seyfert 1.8 and 1.9 AGNs, the third section lists the two LLAMA Seyfert 2 galaxies for which megamaser observations are available, and the fourth section lists the rest LLAMA Seyfert 2 galaxies for which MBH are estimated from the LLAMA MBH–σ⋆ relation. NGC 5128 also has black hole mass estimates from the other methods: MBH 4.5 107 M⊙ from H2 gas kinematics by Neumayer (2010), MBH = 5.5 ± 3.0107 M⊙ from stellar kinematics by Cappellari et al. (2009). We emphasize that our MBH estimate for NGC 5128 is consistent with these results. The σCO(2-0) is used to obtain MBH for NGC 5506 owing to the absence of σCaT. The MBH estimates from ( ⋆ )Braatz et al. (2015), ( • )Greene et al. (2016). We note that we adopted 10% uncertainty for the MBH of NGC 5728 owing to the absence of uncertainty in the related study. We adopted the AV (BLR) estimates obtained from the He II line ratios for MCG-05-23-16, NGC 1365 and NGC 2992 reported by Schnorr-Müller et al. (2016), since this method gives better results for Sy 1.8 and Sy 1.9 galaxies.
